Over 50 years of international research with the Ego Development Model

The E-D-Profile™ is based on decades of research with internationally more than 350 empirical studies. The WUSCT is its foundation and has been developed by Jane Loevinger. That is a standardised sentence completion test.

The E-D-Profile™ offers great reliability and validity as a personality test. It is one of the best validated projective tests worldwide. Numerous longitudinal studies prove the universal development logic (proof of standardized graduation/a single developmental path). As opposed to other aptitude and personality tests, answering according to social preference is not a pitfall.

A decisive advantage compared to other personality tests

As opposed to other aptitude and personality tests, answering according to social preference is not a pitfall. Therefore genuine measurement of the current level of personality development is possible - without conscious manipulation, glossing and independently of its own wishful thinking .
